Row calculation of Matrix

I'm using matrixop to do calculation for both column and row of a 2D matrix. I notice that while there is varcols for column, there is no such function for row. Am I missing something or I have to use matrixtranspose to calculate the variance of rows? I'm using igor pro 6.3.4.1 on win7
MatrixOP is designed for speed. As such it has focus on operations that are aligned with the direction of data storage, i.e., columns.

You do not need to use MatrixTranspose. You can use simple expressions, e.g.,

MatrixOP/o aa=varcols(inmat^t)

Just remember that in this case aa will have dimensions of (1xrows) of the original data.
